Iterator::Util version 0.02
===========================
This module contains many useful utility functions for use with the
Iterator class (q.v.). The inspiration for many of these functions
has been Mark Jason Dominus's lectures and recent book (_Higher Order
Perl_, Morgan Kauffman, 2005).
An "iterator" is an object, represented as a code block that generates
the "next value" of a sequence, and generally implemented as a
closure. Iterator.pm provides a class that simplifies creation and
use of these iterator objects, and provides many general-purpose
iterator functions.
EXAMPLES
$it = irange (1, 3);
$i = $it->value; # returns 1
$i = $it->value; # returns 2
$i = $it->value; # returns 3
$i = $it->value; # throws an Iterator::X::Exhausted exception.
$another_it = imap {$_ * $_} irange (7, 10);
while ($another_it->isnt_exhausted)
{
print $another_it->value, "\n";
}
# The above prints 49, 64, 81, 100 and throws no exceptions.
# Another call to $another_it->value would throw an exception.
DEVELOPMENT STATE
This is a brand-new module. It has a decent test suite, but has
not been extensively field-tested. Therefore, it should be considered
"beta" software, and used with care.
If you find any bugs, or if any behavior of Iterator surprises you,
I would be grateful if you could send me an email message about it.
Thanks.
